iuea'ins ol. a suitable keepor,'one end of which is connected to one face 01 the bunk, and the intermediate portion of which bears on one side of the chock. A-eonnoction is ostab lished lietween the free end ol the keeper and chock, whereby the latter Wi i fall within the bunk and permit the. disiodgnumt of the logs.

it is a well known fact that considerable dillirulty is experienced with devices of this kind in dislodging logs; this is due chiefly to the fact that the parts are so constructed that the weight 0!. thelogs causes the chock to bind against the bunk, so that when the means for holding the latter in upright position s released, the chock fails to respond to the usual outward movement, consequently, it is necessary to'pry or start the logs with a suitable lll1]")l(. ln(l\h, or else lorce the chock outward. This procedure has many dis- :n'lvantagr s, chief among which is that the operator is compelled to approach that side of the bunk from whieh'tlni logs are to be dis- ..-harged and it l'rerpiently happens that the movement of the pic starts at an unexpected mouuiut whereby considerable injury is oitcn iullicted upon tho :rttendant. The present invention aims to remedy this detect by so constructing the chock that the danger of binding will be reduced to a minimum. I

The chock consists of two legs of suitable lengths, one of which is pivoted, as at l hya transversely disposed bolt arrai'iged in the bunk 2. The latter is of a Iii known con striu'tion having; its upper facechanneled. lhe chock is disposed adjaemit either end of lhe hunk and is so positiorn-d that it will fall within the channel when released. As hel'ore stated, one lcgol' the chock liaisons end pivoted within the channel of the bunk, and

the opposite log 3 is provided at one end with a substaidially right angular offset 4. This oll'set is adapted to straddlethc upper edge at one end of the bunk, as clearly shown in Figs. '1 and :2. it will be observed that the oii'se't 4- is not truly right angular: That portion projecting laterally from the end of the leg 3 lies at an obtuse angle to the leg, while the depending extension is bent downwardly and substa ntiallyparallel with the leg 3. From what will subsequently appear, it can he soon that this construction is designed to nected in this position and as s give better results than if the ofiset were truly right angular.- The oppositeend of the leg 3 terminates in an eye or opening 5, while that end of the opposite le 6 of the chock remote from the pivoted en is reduced so as to form a neck? this neck iscurved outwardly and inwardl and extends through the opening 5 of the eg 3, and at its extremity is provided with an enlarged circular head 8 of greaterdiameter Thus it can be seen when the arts are conowh in F' s. 1 to 4 inclusive, the le is will be ermanent combined together, it eingfun the diameter of the neck-7 is considera less than that of the o ening 5, in order'to perinit a relative latera movement between the legs. As .before stated, the terminal of the leg fi is pivoted within the channel of the bunk atapoint adjacent one end thereof, and is-so positioned that when it fallsoutwardly andv within the channel, the head 8 will falllon the upper bunk, as shown in Fig. 3.; When inoperative position, the leg- 6- is br'ought upright, this upright movement ofthe arm will carry with it t e leg 3. The offset of the latter is now ositioned to' straddle the upper and outer e ge of the bunk, as shown in lgS. 1-and2." Owing. to the length of the leg 3, the leg 6 will be-mclined outwardly when the offset engages the end-ofthe bunk, as before described; In orderto secure the parts in this-.position,, 'the following device is emreferring now to Figs. 1 to 3 inclusive it e seen that the end of the bunk is pro-- vided with an inwardly extending and horizontally disposed recess or seat 9. This re cess is dis osed above the floor of the channel and a jacent theu per face of the bunk, and is designed to hol a suitable bar or bolt 10. The length of the latter isconsiderably greater than the width of the bunk and when seated within the recess or seat 9, its 0 pcsite ends willproject beyond-the'outer. aces of the bunk. Each end of the bar 10 terminates in an eye or o ening 11 and secured to one face of, the bun is an eye bolt 12. Connection between the latter and one end of the bolt 10 is established by means of a chain or other flexible element 13. Anchored in that face of the bunk opposite the eye bolt 12 is a similar eye bolt 14 which supports a hook. The shank 15 of the latter terminates at one end in an eye which engages the eye bolt 14, and at its op osite' end has a similar e e. llhe bill 16 o the said hook is preferably right angular in shape having arms of unequal length. The shorter of these arms is provided with an eye, which engages the eye at the" free end of the shank 15, the said short vrarm'terminatin in an enlarged circular head17, which, as before stated, is ro wded with an eye for the reception 0 the than 'the opening 5..

rstood that blyand'outer edge of the I shank 15. Owing to this construction a socket is formed by the circular head 17 and inner end of the long arm socket being sufficient to snugly seat the end link of a length of chain 18, the opposite terminal of whichis secured to that eye of the bar 10- remote from the chain 13. It will be understood that the 7 long arm 16 of the hook is of a sizeto fit slidingly within the end link of .the said chain '18. After the long arm 16 of the hook has been inserted into the end link of the chain 18, the-said long arm may be turned parallel with the shank 15, such movement forcing the link into the socket. It is to-be. understood that the lengths of the chains 13 and 18 are such that, when the chain 18 is in engagement with the socket as hereinbefore described, the element 10, by means of said-- chains 13 and 18, will be held securelyiwithin the recess 9. It is obvious that in order to maintain the parts in this po sition, a clamp or similar device must be employed to encircle the hook and shank, and in 01 'ler to effect mechanism is employed, which is designed to clamp the parts together, as already stated,"

andx-further designed to be operated to release the said parts from the remote end of the bunk, or other words, the operator may dislodge the logs from the bunk by standing on that side of the latter opposite the side over which the logs will fall.

, -By referring now to Figs. 1 and 3, it will be seen that on that face of the bunk to which is secured theforward hook, there is provided one or more eye boltsor guides 19, lying in a plane with the eye bolt 14, or substantially so. These eye bolts receive an operating rod 20, one end of which terminates in a handle 21 which lies adjacent that end .of the bunk remote from the chock, while the" opposite end of the rod terminates in an upwardly ear--v tending arm 21'. The latter is provided with an eye circles the shank 15 of the hook. Owing to 16, the: size of said this purpose, the following or opening 22 which completely'enthe mounting of the rod 20, it can be seen I that it may be reciprocated longitudinally with respect to the bunk, so that the eye portion will slide over the shank 15. itis moved so as to bring the eye 22 to the inner or. connected end of the shank, the hook Thus when may be turned so as to bein the long arm 16 tion, the latter wil perform its function of retaining the logs in the bunk. When the rod 20 1s moved to releasing position and the eye bolt brought from en a ement with the long arm 16, t e weight 0 the logs on the leg 60f the chock will cause the latter to move outwardly and downwardly, whereby a similar movement will be imparted to the leg 3. The latter, owing to the peculiar shape of the offset, before described, will otter little or no resistance to outward .movement. Consequently, as the said arm 3 moves outward and downward, the bar 10 will also be moved from the socket carrying with it the chains 13 and 18. The latter of these chains will rock the long arm of the hook'ouh-vardly, whereby the saidchain will be freed.

From the foregoing, it will be seen that I have provided a device, which is simple in structure, inexpensive to manufacture, and which may be readily a pplied to most forms of bunks now in use.

'. \Vhat is claimed is.:

1. A chock formed of two legs one of which is provided with an opening adjacent one end, and the other having a curved end portion to loosely iit within said opening.
